3D Intracardiac Echocardiography in Mitral Transcatheter Edge-to-Edge Repair : When TEE Is Hard to Stomach

ABSTRACT: Intracardiac echocardiography (ICE) has historically had limited utility in complex structural interventions. Newer 3-dimensional ICE catheters have enhanced imaging and real-time functionality. We present a novel case of mitral valve transcatheter edge-to-edge repair where transesophageal imaging was limited by massive hiatal hernia and where complementary 3D ICE imaging enabled procedural success.

Repeat Mitral Transcatheter Edge-to-Edge Repair for Recurrent Significant Mitral Regurgitation.

Project description:Background There are limited data on repeat mitral transcatheter edge-to-edge repair for recurrent significant mitral regurgitation (MR). Methods and Results We conducted a single-center, retrospective analysis of consecutive patients referred to a second mitral transcatheter edge-to-edge repair after a technically successful first procedure. Clinical, laboratory, and echocardiographic measures were assessed up to 1 year after the intervention. The composite of all-cause death or heart failure (HF) hospitalizations constituted the primary outcome. A total of 52 patients (median age, 81 [interquartile range, 76-87] years, 29 [55.8%] men, 26 [50.0%] with functional MR) met the inclusion criteria. MR recurrences were mostly related to progression of the underlying cardiac pathology. All procedures were technically successful. At 1 year, most patients with available records (n=24; 96.0%) experienced improvement in MR severity or New York Heart Association functional class that was statistically significant but numerically modest. Fourteen (26.9%) patients died or were hospitalized due to HF. These were higher-risk cases with predominantly functional MR who mostly underwent an urgent procedure and exhibited more severe HF indices before the intervention, as well as an attenuated 1-month clinical and echocardiographic response. Overall, 1-year course was comparable to that experienced by patients who underwent only a first transcatheter edge-to-edge repair at our institution (n=902). Tricuspid regurgitation of greater than moderate grade was the only baseline parameter to independently predict the primary outcome. Conclusions Repeat mitral transcatheter edge-to-edge repair is feasible, safe, and clinically effective, especially in non-functional MR patients without concomitant significant tricuspid regurgitation.

Mitral valve surgery after failed transcatheter edge-to-edge repair.

Project description:ObjectiveMitral valve operations for failed transcatheter edge-to-edge repair (TEER) are increasing. This study investigated the indications, surgical procedures, and outcomes after surgery for failed TEER.MethodsWe analyzed records of patients who underwent mitral valve operations after TEER between January 2013 and September 2021. Patient characteristics, clip number and location, indications, timing, surgery type, and outcomes were evaluated.ResultsA total of 41 patients (median age, 77 years; 14 women; median Society of Thoracic Surgeons predicted risk of mortality score, 9.4% [5.6%-12.6%]; and previous cardiac surgery in 21 patients) underwent mitral valve surgery at a median of 8 months (range, 4-16 months) after TEER. One clip was implanted in 24 patients and 2 or more in 17 patients. Indications for surgery were severe mitral regurgitation in 33, severe mitral stenosis in 1 patient, and both in 7 patients. Operations were performed via sternotomy in 37 patients and lateral thoracotomy in 4 patients. The mitral valve was replaced in all patients (bioprosthesis in 35 patients and a mechanical valve in 6 patients). Concomitant procedures were performed in 30 patients. Operative mortality was 5% (observed to expected ratio, 0.53) and did not differ for primary procedures versus reoperations. Echocardiographic follow-up demonstrated no or trivial mitral regurgitation in 34 patients, mild mitral regurgitation in 5 patients, and moderate perivalvular mitral regurgitation in 1 patient with severe mitral annular calcification. At a median follow-up of 1.5 years (interquartile range, 4.7 months-2.7 years), the actuarial survival was 79%.ConclusionsMitral valve replacement can be performed safely after failed TEER with operative mortality lower than expected even in high-risk patients.Video abstract

Transcatheter Edge-to-Edge Repair for Severe Mitral Regurgitation With Double-Orifice Mitral Valve.

Project description:Double-orifice mitral valve (DOMV), a rare congenital heart disease, is the inspiration behind the transcatheter edge-to-edge repair (TEER). Here we report a successful TEER case in a patient with DOMV with severe regurgitation. The patient's symptoms were greatly improved after the procedure.

Prognostic value of hepatorenal function following transcatheter edge-to-edge mitral valve repair.

Project description:BackgroundHepatorenal dysfunction is a strong prognostic predictor in patients with heart failure. However, the prognostic impact of the hepatorenal dysfunction in patients undergoing transcatheter mitral valve repair (TMVR) has not been well studied.MethodsIn consecutive patients who underwent edge-to-edge TMVR at three German centers, the model for end-stage liver disease excluding international normalized ratio (MELD-XI) score was calculated as 5.11 × ln [serum total bilirubin (mg/dl)] + 11.76 × ln [serum creatinine (mg/dl)] + 9.44. Patients were stratified into high (> 11) or low (≤ 11) MELD-XI score of which an incidence of the composite outcome, consisting of all-cause mortality and heart failure hospitalization, within 2 years after TMVR was assessed.ResultsOf the 881 patients, the mean MELD-XI score was 11.0 ± 5.9, and 415 patients (47.1%) had high MELD-XI score. The MELD-XI score was correlated with male, effective regurgitant orifice area, and tricuspid regurgitation severity and inversely related to left ventricular ejection fraction. Patients with high MELD-XI score had a higher incidence of the composite outcome than those with low MELD-XI score (47.7% vs. 29.8%; p < 0.0001), and in multivariable analysis, the high MELD-XI score was an independent predictor of the composite outcome [adjusted hazard ratio (HR) 1.34; 95% confidence interval (CI) 1.02-1.77; p = 0.04). Additionally, the MELD-XI score as a continuous variable was also an independent predictor (adjusted HR 1.02; 95% CI 1.00-1.05; p = 0.048).ConclusionsThe MELD-XI score was associated with clinical outcomes within 2 years after TMVR and can be a useful risk-stratification tool in patients undergoing TMVR.

Acute Reduction in Left Ventricular Function Following Transcatheter Mitral Edge-to-Edge Repair.

Project description:Background Little is known about the impact of transcatheter mitral valve edge-to-edge repair on changes in left ventricular ejection fraction (LVEF) and the effect of an acute reduction in LVEF on prognosis. We aimed to assess changes in LVEF after transcatheter mitral valve edge-to-edge repair for both primary and secondary mitral regurgitation (PMR and SMR, respectively), identify rates and predictors of LVEF reduction, and estimate its impact on prognosis. Methods and Results In this international multicenter registry, patients with both PMR and SMR undergoing transcatheter mitral valve edge-to-edge repair were included. We assessed rates of acute LVEF reduction (LVEFR), defined as an acute relative decrease of >15% in LVEF, its impact on all-cause mortality, major adverse cardiac event (composite end point of all-cause death, mitral valve surgery, and residual mitral regurgitation grade ≥2), and LVEF at 12 months, as well as predictors for LVEFR. Of 2534 patients included (727 with PMR, and 1807 with SMR), 469 (18.5%) developed LVEFR. Patients with PMR were older (79.0±9.2 versus 71.8±8.9 years; P<0.001) and had higher mean LVEF (54.8±14.0% versus 32.7±10.4%; P<0.001) at baseline. After 6 to 12 months (median, 9.9 months; interquartile range, 7.8-11.9 months), LVEF was significantly lower in patients with PMR (53.0% versus 56.0%; P<0.001) but not in patients with SMR. The 1-year mortality was higher in patients with PMR with LVEFR (16.9% versus 9.7%; P<0.001) but not in those with SMR (P=0.236). LVEF at baseline (odds ratio, 1.03 [95% CI, 1.01-1.05]; P=0.002) was predictive of LVEFR for patients with PMR, but not those with SMR (P=0.092). Conclusions Reduction in LVEF is not uncommon after transcatheter mitral valve edge-to-edge repair and is correlated with worsened prognosis in patients with PMR but not patients with SMR.
